A multi-directional input device normally detects a housing, an operating body rotatably provided on the housing, two cams that rotate as the operating body tilts, and the amount of rotation of the cams and outputs a corresponding signal. and an output sensing device. In order to make the tilting motion of the operating body smoother, a spherical part is usually provided at the bottom of the operating body. By providing a grip portion with a large volume in a part, it is easy to control the operation of the operation body via the grip portion by manual operation. Assembling directly with the housing is relatively difficult. In order to facilitate the assembly of the operation body and the housing, some conventional multi-directional input devices employ a method of providing a larger opening in the housing. Dust tends to accumulate on the Some other multi-directional input devices employ a method in which the grip part and the operation body are arranged separately and the operation body and the spherical part are integrally formed. Since the range of movement when operating the part is large, the grip part easily falls off. There is also a multi-directional input device that employs a method in which a grip portion and an operation body are molded integrally, and an operation body and a spherical part are separately molded. In such a multi-directional input device, since a large force is applied to the connecting portion between the operating body and the spherical part, the operating body tends to fall off, and it is difficult to reattach the operating body after falling off. Continuous use becomes impossible.

1 and 2, FIG. 1 is a cross-sectional view of one embodiment of the multi-directional input device of the present invention, and FIG. 2 is an exploded view of one embodiment of the multi-directional input device of the present invention.

In an embodiment of the present invention, the multi-directional input device comprises:
a first housing 100 provided with a first housing space 110 having a first opening;
an operation body 200 having an operation part 230 provided so as to protrude from the first opening so as to be tiltable at one end thereof, and extending into the first accommodation space 110 at the other end thereof and provided with an engagement part 210;
a hemisphere 300 provided with a mounting hole 310 for inserting the engaging portion 210;
a hook portion 400 that is provided on the inner wall of the mounting hole 400 and elastically contacts the engaging portion 210 for fixing the engaging portion 210 in the mounting hole 310;
a return mechanism 500 for returning the operating body 200 to the neutral position;
a push switch mechanism 600 that is electrically operated by pressing the operation body 200;
a first cam 710 and a second cam 720 which are arranged outside the first housing 100, rotate as the operation body 200 is tilted, and whose rotation axes are horizontal and perpendicular to each other;
a first detection mechanism 810 for detecting the rotational movement of the first cam 710 and a second detection mechanism 820 for detecting the rotational movement of the second cam 720;
have

A multidirectional input device according to one technical solution of an embodiment of the present invention includes a first housing 100, an operating body 200, and a hemispherical body 300. The first housing 100 has a first opening. A housing space 110 is provided, the operating body 200 is provided movably so as to protrude from the first opening, and an engaging portion 210 is provided at one end of the operating body 200 located in the first housing space 110, A mounting hole 310 corresponding to the engaging portion 210 is provided in the hemispherical body 300 , and the engaging portion 210 is inserted into the mounting hole 310 to realize fixation of the operating body 200 and the hemispherical body 300 . A hook portion 400 is further provided on the inner wall of the mounting hole 310 , and when the engaging portion 210 is inserted into the mounting hole 310 , the hook portion 400 elastically contacts the side wall of the engaging portion 210 . Since the engaging portion 210 is a rigid body, the hook portion 400 is elastically deformed in the direction away from the engaging portion 210, and the hook portion 400 tends to recover from the deformation, so a reaction force is generated on the side wall of the engaging portion 210. By doing so, it is possible to firmly fix the engaging portion 210 in the mounting hole 310 and reduce the probability that the operating body 200 will fall off the hemispherical body 300 .

In this embodiment, the hook portion 400 and the hemispherical body 300 may be integrally molded or designed separately. The elastic contact between the hook portion 400 and the engaging portion 210 may be realized by the hook portion 400 itself being elastic, such as the hook portion 400 being a protrusion made of an elastic material. Although a non-elastic material is used, it may be realized by making the structure of the hook part 400 elastic. The mounting hole 310 may or may not pass through the hemisphere 300 . 1 to 4, in this embodiment, the multidirectional input device further includes a first cam 710 and a second cam 720 that rotate as the operation body 200 is tilted. As cam 720 rotates, the position of first cam 710 and second cam 720 is changed by sliding the corresponding slider on circuit board 620 to change the electrical connection position between the contacts on the slider and circuit board 620 . The change, that is, the specific position of the tilted state of the operating body 200 is received by the control unit of the multi-directional input device. In this embodiment, a clamping groove is provided below the rotating shaft of the first cam 710, and the first cam 710 clamps the first clamping part provided in the first detection mechanism 810 via the clamping groove. . When the first cam 710 rotates due to the tilting motion of the operating body 200 , the first cam 710 causes the first detection mechanism 810 to slide on the circuit board 620 , thereby electrically connecting the first detection mechanism 810 and the circuit board 620 . By changing the position of the connection contact, the circuit board 620 can detect the amount of rotation of the first cam 710 and further obtain the amount of rotation of the operating body 200 in one direction. A pinching groove is provided below the rotating shaft of the second cam 720, and the second cam 720 pinches the second pinching portion provided in the second detection mechanism 820 via the pinching groove. When the second cam 720 rotates due to the tilting motion of the operating body 200 , the second cam 720 causes the second detection mechanism 820 to slide on the circuit board 620 , thereby electrically connecting the second detection mechanism 820 and the circuit board 620 . By changing the position of the connection contact, the circuit board 620 can detect the amount of rotation of the second cam 720 and further obtain the amount of rotation of the operating body 200 in another direction. The circuit board 620 can combine the amounts of rotation of the operation body 200 in two directions, and further obtain the rotation direction and the amount of rotation of the operation body 200 .

Preferably, a plurality of hook portions 400 are arranged on the inner periphery of mounting hole 310 .

5 to 7, in this embodiment, since a plurality of hook portions 400 are arranged on the outer periphery of the engaging portion 210, the engaging portion 210 can be fixed more firmly within the mounting hole 310. Furthermore, the operation body 200 can be made more difficult to fall off. Specifically, in this embodiment, four hook portions 400 are provided on the inner wall of the mounting hole 310, and two hook portions 400 form one set. The engaging portion 210 in the mounting hole 310 is sandwiched by arranging the 400 so as to face each other.

Further, the hook part 400 is an elastic arm 401, the first end of the elastic arm 401 is integrally formed with the inner wall of the mounting hole 310, and the second end of the elastic arm 401 extends along the inserting direction of the engaging part 210. A space is formed with the inner wall of the mounting hole 310, and in a state in which the engaging portion 210 is inserted into the mounting hole 310, the engaging portion 210 abuts against the elastic arm 401, thereby moving the elastic arm 401 in a direction in which the space is reduced. Transform into

5 to 7, in this embodiment, the hook part 400 is an elastic arm 401, the first end of the elastic arm 401 is fixed, and the second end is free and directed into the mounting hole 310. By forming a space with the inner wall of the mounting hole 310 while extending obliquely through the elastic arm 401, the elastic arm 401 forms an elastic structure. When the engaging portion 210 is inserted into the mounting hole 310, the end of the engaging portion 210 first contacts the first end of the elastic arm 401, and when the engaging portion 210 is subsequently inserted, the engaging portion 210 When the contact point between the end portion and the elastic arm 401 slides toward the second end of the engaging portion 210, the second end of the elastic arm 401 is deformed in a direction away from the engaging portion 210, Since 401 tends to recover from its own deformation, elastic arm 401 can apply force to engaging portion 210 to secure engaging portion 210 within mounting hole 310 . The specific shape of the elastic arm 401 is not limited here because it can be designed and adjusted as necessary as long as it satisfies the functional requirements.

Further, the engaging portion 210 is provided with a fitting groove 211 corresponding to the elastic arm 401, and by fitting the elastic arm 401 into the fitting groove 211, the operation body 200 and the hemispherical body 300 are fixed.
And/or, the operating body 200 is provided with a positioning portion 220 directed in the insertion direction, and when the engaging portion 210 is inserted into the mounting hole 310, the positioning portion 220 abuts the upper surface of the hemispherical body 300. Further insertion of the operating body 200 into the mounting hole 310 is restricted.

5 to 7 , in this embodiment, the engaging portion 210 is provided with a fitting groove 211 corresponding to the hook portion 400 , and the shape of the fitting groove 211 is the shape of the hook portion 400 . Each hook portion 400 is provided with a corresponding fitting groove 211, and when the engaging portion 210 is inserted into the mounting hole 310 to a desired position, the hook portion 400 is fitted. Since the hook portion 400 and the engaging portion 210 can form an interference fit by being fitted in the matching groove 211, the engaging portion 210 is prevented from coming out of the mounting hole 310, and the engaging portion 210 is mounted. Robustness within the hole 310 is improved. Specifically, in this embodiment, the shape of the fitting groove 211 is set to correspond to the shape of the elastic arm 401 , and the bottom of the fitting groove 211 is located on the side that fits with the second end of the elastic arm 401 . It is inclined so that the depth is greater than the depth of the side that engages with the first end of the elastic arm 401 . In this embodiment, unless the four elastic arms 401 provided on the outer periphery of the engaging portion 210 are destroyed, the operating body 200 cannot fall off the hemispherical body 300 .

5 to 7 , in this embodiment, the operating body 200 is provided with a positioning portion 220, and the positioning portion 220 may be an independently provided protrusion. It may be formed by changing the cross-sectional diameter of the body 200 itself or by changing the cross-sectional shape. In this embodiment, since the mounting hole 310 penetrates the hemispherical body 300 , when the engaging portion 210 is inserted into the mounting hole 310 , the hook portion 400 is fitted into the fitting groove 211 , so that the mounting is performed. The movement of the engaging portion 210 in the direction of withdrawing from the hole 310 is restricted, but the movement of the engaging portion 210 in the direction extending into the mounting hole 310 is not restricted. If force continues to be applied to the operating body 200, a larger portion of the operating body 200 may enter the mounting hole 310 and penetrate the hemisphere 300, possibly damaging other parts in the first receiving space 110. Therefore, by providing the positioning portion 220, the relative position between the operation body 200 and the hemisphere 300 can be fixed.

Preferably, the push switch mechanism 600 includes:
It consists of a metal switch 610 and a circuit board 620 provided with a disk-shaped reversing mechanism, and a pusher 630 for pushing the switch 610,
The pusher 630 is arranged coaxially with the operation body 200 and has a substantially cylindrical shape. A convex portion 632 for pushing the switch 610 is formed.

1, 2, 8 and 9, in this embodiment, the push switch mechanism 600 includes a switch 610, a circuit board 620 and a pusher 630. As shown in FIG. When the operating body 200 is pushed, the engaging portion 210 approaches the upper end of the pusher 630 until it comes into contact with the upper end of the pusher 630. As the operating body 200 is continuously pushed, the operating body 200 presses the pusher 630, A convex portion 632 at the lower end of the pusher 630 activates the switch 610 below the pusher 630 , and the switch 610 realizes electrical connection. can be received. Specifically, in this embodiment, a circuit board 620 as a control unit is provided at the bottom of the first accommodation space 110, and the switch 610 is a movable contact plate. under normal conditions. The movable contact plate arches away from the first housing 100 so that the contacts on the movable contact plate do not contact the contacts on the circuit board 620 . When the second end of the pusher 630 is deformed toward the movable contact plate as the operating body 200 is pushed, the movable contact plate is deformed by receiving force, and the arcuate curve of the movable contact plate is pushed downward, and the movable contact plate is deformed. The contacts on the top make contact with the contacts on the circuit board 620 to achieve electrical connection. When the external force applied to the operating body 200 stops, the operating body 200 returns due to the action of the coil spring 530 , and at the same time the movable contact plate recovers from its own deformation, and the contacts on the movable contact plate move away from the contacts on the circuit board 620 . Since the electric connection is cut off by separating, the control unit can recognize that the operation of the operation body 200 by the person has stopped. Since the operation of the operating body 200 itself is a combination of tilting and vertical movement, if the operating body 200 directly actuates the switch 610, the switch 610 is likely to be erroneously contacted or contact failure occurs. By causing the switch 610 to recognize only the up-and-down pushing motion of the operating body 200, it is possible to achieve more accuracy. In this embodiment, when the engaging portion 210 and the pusher 630 come into contact with each other, they are engaged with the hemispherical concave portion 631 via the hemispherical portion 212 . When the portion 210 contacts the upper end of the pusher 630 , the engaging portion 210 moves the pusher 630 downward and rotates to change the contact position between the engaging portion 210 and the pusher 630 . By providing the hemispherical portion 212 and the hemispherical recessed portion 631, the operation of the engaging portion 210 when it comes into contact with the pusher 630 and rotates with respect to the pusher 630 is made smoother, and the operation of the operating body 200 is controlled by hand. It is possible to improve the operational feeling at the time of doing. Specifically, in this embodiment, the semispherical concave portion 631 is provided on the upper surface of the pusher 630 , and the semispherical portion 212 is formed integrally with the operating body 200 . The specific shape of the convex portion 632 is not limited here because it can be designed and adjusted as necessary as long as it satisfies the functional requirements.

A coil spring 530 has one end abutting against the coil spring support 510 and the other end urging the plate 520 to abut the plate 520 against the circular flat portion 301 .

1, 2, 10 and 11, in this embodiment, the return mechanism 500 includes a coil spring pedestal 510, a plate 520 and a coil spring 530. As shown in FIG. The coil spring pedestal 510 is fixed to the first housing 100, the coil spring pedestal 510 is provided with a second escape port corresponding to the pusher 630, the lower end of the pusher 630 is fitted in the coil spring pedestal 510, The upper end of the pusher 630 passes through the second escape port to contact the engaging portion 210 of the operating body 200 . The cooperation of the plate 520 and the coil spring 530 restores the operation body 200 from the tilted state to the vertical state when no external force is applied, and improves the feedback feeling transmitted to the hand when the operation body 200 is tilted. . Plate 520 is movably disposed between operating body 200 and coil spring cradle 510 , coil spring 530 connects coil spring cradle 510 and plate 520 , and coil spring 530 biases plate 520 . The plate 520 is brought into contact with the circular plane portion 301 of the hemispherical body 300 by pressing. Coil spring 530 may be a normal compression coil spring or a conical compression coil spring. Specifically, in this embodiment, a conical compression coil spring is adopted as the coil spring 530 , one end of the conical compression coil spring with a large diameter is brought into contact with the plate 520 , and one end with a small diameter is brought into contact with the coil spring support base 510 . by providing the conical compression coil spring with greater lateral stability and reducing its tendency to flex. It is possible to make it easier for the operating body 200 in the tilted state to return to the vertical state.
